Analysis Of Hands-On Science With Thy Circuits

In the two articles and the video I read and watched, they all had some sort of description of electricity. I think that the purpose of each is to get the reader or viewer to learn something about electricity. In Energy Story the main idea was to teach and tell the reader about how we use appliances or things that use electricity almost every day and sometimes without even knowing. Energy Story also teaches you about atoms and how they are made up of protons, neutrons and electrons. The passage gives you an example to make atoms more understandable. The passage states, " Electrons spin around the center, or nucleus, of atoms, in the same way the moon spins around the earth." In "Conducting Solutions", the central idea or purpose is to teach about solutions and how some can conduct electricity better than others. The passage also talks about ions. According to the article ions are atoms or small groups of atoms that have an electrical charge. If a solution has more ions than the solution can conduct electricity better than a solution that contains less ions. Pure water contains few ions, but if it is mixed with salt or other high ion …show more content…
The speaker talks about her daughter and how she teaches her about electricity and circuits. When the speaker wanted to make something easy and simple for her daughter to use for creating circuits, she came across two favorite recipes for play dough. The recipe that contained salt conducted electricity, but the one that contained sugar did not. This is because salt has ions in it and ions conduct electricity. This is how the speaker's daughter made small circuits, by taking two pieces of the salt dough and one piece of the sugary dough and put it in the order in which the sugary dough was stuck between the salt
